Filter by:The purpose of this study is to determine whether prazosin will: - reduce the incidence of nightmares and sleep disturbance - increase functioning and sense of well being in combat-trauma exposed Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Veterans.
The purpose of this study is to determine whether a newly developed, brief cognitive behavioral intervention, relative to supportive counseling, is effective in reducing acute stress disorder (ASD) and preventing post traumatic stress disorder (PTSD) and depression.
The ultimate goal of this work is to establish a method for control bleeding after tonsillectomy in awake children. Treatment of post-tonsillectomy bleeding in children typically requires general anesthesia with currently used electrocautery techniques. Micropolysaccharide hemosphere technology is a unique absorbable agent that helps clot form. These hemospheres consist of 100% purified plant starch that enhances natural clotting by concentrating blood solids such as platelets, red blood cells, and blood proteins on the particle surfaces to form a gelled matrix. This device provides painless, non-irritating control of bleeding, and has been used effectively for control of nosebleeds in awake adult patients. This device, however, has not been tested in the tonsillar fossae in children; thus, this study is performed to determine if at least 50% of children with bleeding tonsillar fossae can be spared rescue treatment with electrocautery.
Efavirenz causes neuropsychiatric side effects and sleep disturbance, including vivid dreams, dizziness, and abnormal tiredness. These symptoms are frequent during the first weeks of treatment, with subsequent attenuation but may not completely resolve even years after efavirenz initiation. The investigators plan a four week, randomized, placebo-controlled, double-blind study. In group 1, efavirenz will be replaced with efavirenz placebo plus raltegravir, in group 2, efavirenz would be continued, and raltegravir placebo given in addition. After two weeks, patients in group 1 would switch to the regimen of group 2, and vice versa. The primary endpoint of the trial will be patient preference. Sleep quality, daytime sleepiness, and anxiety will also be investigated.
The aim of this exploratory randomized, placebo controlled study is to evaluate the efficacy of Circadin® 2mg in patients with mild to moderate Alzheimer Disease (AD) treated with the acetylcholinesterase (AChE) inhibitor. The effects of add-on Circadin® 2mg vs. placebo on the decline in cognitive skills and global functioning, as well as on daytime somnolence and will be assessed.
RATIONALE: Methadone hydrochloride may reduce chronic neuropathic pain in patients with cancer. PURPOSE: This phase I trial is studying the side effects and best dose of methadone hydrochloride as first-line therapy in treating patients with chronic neuropathic cancer pain.
This research project consists of a three part study with five embedded sub studies. The first study phase identifies "body rhythms" of sleepiness/wakefulness and of melatonin levels for each subject (including sub-study 1). The second study phase identifies the optimum dose and timing of melatonin for regulating each individual's 24-hour sleep/waking cycle (including sub-study 2). The third study phase introduces a new independent variable, light (including sub-studies 3 and 4). Sub-study 5 is an optional longitudinal study. Sub-study 1 looks at how keeping a regular sleep schedule affects the body's natural rhythm. Sub-study 2 looks at how individuals metabolize melatonin. Sub-study 3 tests how individuals' endogenous melatonin production responds to bright outdoor light and Sub-study 4 tests a previous finding that artificial bright light exposed daily behind the knee can regulate the body clock. Sub-study 5 is an optional longitudinal study, an extension of the first study stage, for subjects whose rhythms are not clearly free-running.
The purpose of this study is to compare the sleep quality of patients with psoriasis to patients without psoriasis.
The purpose of the study is to demonstrate the effect of Lyrica on Wake after sleep onset in subjects with fibromyalgia with sleep maintenance disturbance (on polysomnogram)
The purpose of this study is to determine whether melatonin can improve sleep, quality of life and markers of heart failure in patients with heart failure.
